Q206 Feed rate for plunging?: Traversing speed of
the tool in mm/min when plunging to depth. Input
range 0 to 99999.999, alternatively FAUTO, FU, FZ
Q338 Infeed for finishing? (incremental): Infeed in
the spindle axis per finishing cut Q338=0: Finishing
in one infeed. Input range 0 to 99999.9999
Q385 Finishing feed rate?: Traversing speed of the
tool in mm/min during side and floor finishing. Input
range 0 to 99999.999, alternatively FAUTO, FU, FZ
Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface Input range
0 to 99999.9999; alternatively PREDEF
Q203 Workpiece surface coordinate? (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
Q204 2nd set-up clearance? (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
Q366 Plunging strategy (0/1/2)?: Type of plunging
strategy:
0 = vertical plunging. The TNC plunges
perpendicularly, regardless of the plunging angle
ANGLE defined in the tool table
1 = No function
2 = reciprocating plunge. In the tool table, the
plunging angle ANGLE for the active tool must be
defined as not equal to 0. The TNC will otherwise
display an error message
Alternatively PREDEF
Q369 Finishing allowance for floor? (incremental):
Finishing allowance for the floor Input range 0 to
99999.9999
Q439 Feed rate reference (0-3)?: Specify what the
programmed feed rate refers to:
0: Feed rate with respect to the tool center point
path
1: Feed rate with respect to the tool edge, but only
during side finishing, otherwise with respect to the
tool center point path
2: Feed rate refers to the tool cutting edge during
side finishing and floor finishing; otherwise it refers
to the tool path center
3: Feed rate always refers to the cutting edge
